DRC classes have an entity_sense method to determine (in a specific PAPR sense) the presence or absence of a device plugged into a DRC. However, we only have one implementation of the method, which explicitly tests for different DRC types. This changes it to instead have different method implementations for the two cases: "logical" and "physical" DRCs. While we're at it, the entity sense method always returns RTAS_OUT_SUCCESS, and the interesting value is returned via pass-by-reference. Simplify this to directly return the value we care about Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Reviewed-by: Michael Roth <mdroth@linux.vnet.ibm.com> Acked-by: Michael Roth <mdroth@linux.vnet.ibm.com>
